How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2. REGISTER In normal Asp. GUI and the server code. But Asp. Net MVC is a framework that Microsoft has built in a completely unit testable way. Asp. Net MVC applications because the Models, Views and Controllers are very loosely coupled.

It happens this way, first create a test case, fail it, do the implementation, ensure the test case success, re factor the code and then continue with the cycle again as indicated in Fig 1. Fig 1. 0 Test Driven Development. TDD also states that every code which is deployed to production should be covered by the unit test case. The best practices in writing the unit test cases are to follow the F. I. R. S. T principles. Here is a brief explanation for each of them. Fast Write the unit test cases by keeping their performance in mind. This is required because you will have to run thousands of them during every release. Isolated Each test case to be isolated to a particular behavior i. A test case should be broken down into multiple smaller ones for this purpose. Repeatable The test case should be stable so that it provides the consistent results over multiple runs. Self validating The test should result in a pass or a failure. EnableUrlAuth.png' alt='What Is The Purpose Of The Code-Behind Files In Asp.Net' title='What Is The Purpose Of The Code-Behind Files In Asp.Net' />There should not be any ambiguity scenarios with assertions. Timely This is more important for TDD as the test cases should be created before the actual implementation is. Symbian S60 Video Player. TDD with Asp. Net MVCAsp. Net MVC is a perfect adoption for unit testing since the entire server code is embedded in the controllers, which are de coupled from other layers like GUI View. When you create an Asp. Net MVC application Visual Studio by default will prompt for adding a Unit Test case project as shown in Fig 2.

Fig 2. 0 Prompt for adding a Unit Test case project. Testing the Controller. Let us take a look at few samples that will demonstrate writing the unit test cases for the Controllers in an As. Net MVC application. Create an Asp. Net MVC application in Visual Studio 2. Lets assume that we are creating an online movie store application. In the MVC application create a controller named Movie. Store. Controller, a model named Movie for now we dont create any views, which can be done at a later point in time. The requirement is to display a welcome message to the user on the Movie. Store index and to list the movies from the application database. As it is a TDD we should write the test case first for the requirement and then proceed with the implementation. In the Unit. Test project add a unit test class named Movie. Store. Controller. Test. As a standard the naming convention followed in MVC for the unit test classes is the controller name followed by Test. First lets concentrate on building the functionality for the welcome message requirement. The following code is the test case to validate the welcome message. Tdd. With. Mvc. Tests. Test. Class    publicclass. Movie. Store. Controller. Test. Test. Method        publicvoid Movie. Store. Provides. Correct. Welcome. Message. Movie. Store. Controller movie. Controller new. Movie. Store. Controller            View. Result result movie. Controller. Index as. View. Result            Assert. Are. EqualWelcome to the movie store, result. View. Bag. Message. The index returns the View. Result, as the MVC controller methods will return Views, unlike normal Asp. C methods. Running the above test case will fail and let us implement the Index method in the controller as shown below, allowing the functionality to pass. This is how the items in the controller View. Bag can be unit tested. Tdd. With. Mvc. Controllers. Movie. Store. Controller Controller. Action. Result Index. View. Bag. Message Welcome to the movie store             return View. Let us now write the unit test case for the Movie list functionality. Test. Method        publicvoid Movie. Store. Returns. The. List. Of. Movies. Movie. Store. Controller movie. Controller new. Movie. Store. Controller            View. Result result movie. Controller. Movies as. View. Result            var movies result. Model as. Listlt Movie             Assert. Are. Equalmovies. Count, 2. 00. public. Action. Result Movies. Data. Access. Get. Movies. From. Database                       return Viewmovies. Now go and do coding until the above test case goes for a pass. Below is the implementation, which fetches the movies from the database and encapsulate it with the View. Action. Result Movies. Data. Access. Get. Movies. From. Database                       return Viewmovies. Running the unit test case will succeed as the current movie count is 2. But what if a few more movies are added to the database Or what if the database connection in the test case execution environment does not go through The test case will start failing. The intention of the unit test case is now broken. The intention was to test only the controller method if it returns the list of movies and not to test the number of records in the database or the database connectivity. This is when you need to still decouple the dependent classes. One of the ways to achieve it is by doing dependency injection. To correct the above unit test case, let us introduce dependency injection. Create an interface to mock data access object and inject it while creating the controller instance. Here is the code for interface and the test case using the mock object. IData. Access. Manager. Listlt Movie Get. Movies. From. Database. In the test method notice that the mock object is being injected into the controller constructor. Test. Method        publicvoid Movie. Store. Returns. The. List. Of. Movies. Movie. Store. Controller movie. Controller new. Movie. Store. Controllernew. Mock. Data. Access. Manager            View. Result result movie. Controller. Movies as. Are. Equalmovies. Count, 2. Now in the implementation we will have to make the changes to use the actual data access class during the application execution and to use the mock object only during unit test case. Following is the code to do it exactly as required. Notice that the default constructor is explicitly injecting the concrete data access object. IData. Access. Manager movies. Data.

For testing the Views you may have to use automation testing software like Selenium, Coded UI, etc.
